This invention pertains toa method of reconstructing worn out discarded railwa'y'locomotive journal boXes, and the method pertains particularly to the procedure of reconstructing locomotive journal arched, type. e An object of the invention'is to'salvage a discarded journal-box that has become so worn as to be. of no further use, by the i process of machining the surfaces thereof to true them as well as to rebore them for new brasses or bearing parts, and to attach per- .manently-to said box a so called. filler-block for supporting said brasses.

Another object oftheinvention is .to machine each inner surface of ajournal-box and weld thereto a filler-block for carry ing new brasses. r

Still another object isthat of machln ng certain surfaces of ajournal-box to create a shoulder on each of two facing surfaces thereof and then weld a filler-block to each said surface supporting the same on the said shoulder. l i T t: 7

In my pending patent application for a journal bearing filed in the U. S. Patent Office May 28th, 1926-, under Serial No. 112,221 there: is illustrated and described the article, ajour-nal-boX,togetherwith a filler-block for block by welding;v oXes of the attachment to the same. This present invention relates to the manner of treatment of the box. and the method of securing the filler-' When a journal-box has become so .worn as to be unfit for use I am enabled to recon- .structit so that it is good for many thousands of miles of service while'at the same time providing advantages in the use of certain added parts having no-part-in the present application except to show the use and value of the filler-block and the particular manner of its attachment to the box.

In Figure 1 is illustrated a journal-box 1 as of a form in use on railwaysat the present time wherein it is observed that within the v central arched opening thereof there are. two p'rominences 2, and that thefacing surfaces of the walls within said opening below the prominences are, in this instance, of an irregular formQ g i -In my method of 5 preferablyleaving a shoulder or ledge 6 as indicated in Figure 2 which figure shows "the same box machined as described,"and in which, also, the numeral 7 designates a vertical surface 'at' each side of the 'arched open- 'ing 8 which meets the said ledge or shoulder '6. The shoulders thus formed extend in the direction of each other and parallel surfaces 9' drop therefrom as shown all in agreement with-the said dotted lines of Figure 1. Be- 7 treatment'of the box these said prominences 2 and the said irregular surfaces are removed by machining away the -metal substantially alongthe dotted lines 3,4,

sidesthu's machining these surfaces the metal 1 of the filler-block designated at 12. Thede-- scribed treatment of the journal-box rezmoves metal therefrom within the arched opening so that a better form. of support for the crown brass and. certaln sldebrasses may be provided and by which a wedge may be employed "to adjust the named brasses.

The block 12 as shown in Figure 4f is substantially flat but having on one of its surfaces at What may be termed its top edge an enlargement 18 having a machined under surface 14 to lie upon the machined ledge or shoulder 6 of the box. In addition, the block has a series of holes 15 which in this instance extend'through the said enlargement 13 which preferably taper from what may be termed the outer surface of the block toward the inner surface that is to lie upon the sur face 7 of the box as may be seenin Figure 2. As usually constructed a journal-box has depending cars 16 to accommodate a bolt, not shown, for supporting a grease cellar closure,

not shown, and the filler-block therefore has corresponding ears 17, by choice, although theseiare not necessarily concerned in the present invention.

The block 12 when placed in position as shown in said Figure 2 is below the axial center of the journal box and receives upon its top a wedge 18 for supporting a quarter or side brass 19 opposite the axial center of the'journal box space and upon which brass rests one end of a crown brass 20 previously referred to. That the wedge 18 may function to raise the brasses 19 and 20 the top edge of the filler block is beveled at 21 throughout its length, as shown best in Figure 3, being also beveled laterally downwardly and inwardly toward the surface 7 of the box as at- 21, Figure 2.

The block is attached or secured to the box preferably by electric or oxy-acetylene welding in substantially the following .manner: The welding-metal is fused upon and atprovide further built-up metal at 24, in ad dition to which spot welding may :be resorted to at 25 where the edges of the box and block adjoin, or the welding-metal may be built up along the entire line of separation. of said box and block in lieu of or in addition to the spotting of the same. 7

Although the shoulder or ledge 6 and the enlargement 13 are shown to rest one on the other, these may not be used although their employment is preferable as an additional support to the welded-in plugs 22 for supporting the brasses resting upon the block.
